Data Fusion

Robotics Above, On, and Underwater

Demo-ing Drones at UAS Colorado’s “Robotics on the Rez” Event In the September 10th issue of Pangaea we talked about Future Prepping: getting ready for the next generation of geospatial technology. I’d like to add another educational resource to that list: product demos. Product demonstrations are a great way to get a hands-on look at...

Clear Scanning on the Clearwater

Above: The survey included collecting bathymetric data on the river bottom and bridge substructure with multibeam sonar as well as capturing above- and below-waterline mobile mapping data with the Leica Pegasus: Two mobile sensor platform. Two well-paired engineering firms used high-accuracy mobile mapping to combine bathymetry and lidar data for a fast-turnaround topographic survey of...
